1989 5.0 hot weather stall
Any ideas on what would cause a 5.0 to stall when temps get above 70? replaced both fuel pumps(used but good), ignition module, cap, rotor, plugs, plug wires, both fuel filters and fuel pressure reg. Had it for a month now, had sat for a year before I bought it. Reported to me by previous owner it never has ran right. Always short on power.
MAP sensor??? At least that is my best guess with information provided.. Does it do it when you first crank it up?? Or after it warms up? What are the weather conditions like outside? any moisture? Does it do it every time the temperature is above 70?
vapor lock, i had that problem on my bronco, i had to modify the exhaust so that it went nowhere near the gas tank. you can do it cheap through autozone or have it done right by a muffler shop.
fuel injected cars dont vaporlocl like the carbuatored cars did,check the fuel pressure on the rail going to the injectors,looks like a tire valve in the line.
